Study on the variations of viscosity and interfacial tension of polymer/surfactant binary flooding in porous media plays a guiding role. In order to study the variation of the system in porous media, flood test is designed which uses four kinds of injected slugs and three kinds of sand filling tubes to study the variation of viscosity and interfacial tension of the system. The results show that under the same injection speed and the flow distance, the greater slug injected, the lower minimum interfacial tension obtained, a longer time maintained and a higher viscosity retained. Under the same injection speed and injected slug, the longer the flow distance, the lower minimum interfacial tension obtained, a longer time maintained and a higher viscosity retained. These results have an important guiding role for the binary system of injection plan design., correspAuthors=null, authorNote=null, correspAuthorsNote=null, copyrightStatement=null, copyrightOwner=null, extLink=null, articleAbsUrl=null, sourceXml=null, magXml=null, pdfUrl=null, pdf=YfrdD8G8h21e+XexKQbyCw==, pdfFileSize=2930268, pdfExtLink=null, richHtmlUrl=null, mobilePdfUrl=null, reviewReport=null, pdfFirstPage=null, abstractGraph=null, abstractGraphContent=null, abstractVideo=null, citation=null, cebUrl=null, magXmlContent=null, mapNumber=null, authorCompany=1.
